AGRAFFE F SPECIFICATION forming part of Letters Application liled May Toon whom it may concern:

Be it known that I, AUGUSTUS BAUS, of the city, county, and State of NewYork, have invented a new and Improved Agraffe, of which the followingis a full, clear, and exact description.

The object of my invention is to provide a new and improved agraffewhich is so constructed that under no circumstances the strings can slipin the same, and are at all times held firmly and securely, and by thussecurely holding the said strings the tuningpins are relieved of a partof the immense strain they are subjected to in pianos of the usualconstruction, and thereby necessitating less frequent tuning of theinstrument. The invention consists in the construction and arrangementof parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecolresponding parts in all the figures.

Figure 1 is a face View of my improved agraffe. Fig. 2 is a side view,parts being broken out and others shown in section; and Fig. 3 is a faceview of an agraffe for double strings, and Fig. 4 is a perspective viewof an agraffe for treble strings.

is provided with a vertical groove or recess,

D, forming two upwardly-projecting prongs,

E and E. In each prong E or E one, two,

or three apertures, a. are formed, according 5 to the number of stringsthe agraft'e is to hold. The apertures a in the two prongs are arrangedat dilferent elevations, and the apertures are inclined, as shown. Theouter ends of the apertures a are widened or enlarged, as shown, 40 soas to prevent cutting the strings.

The agratfes are screwed into the wrestplank or into the metal plate,the agratfes screwed into the wrest-plank having long screws and thosescrewed into the plate hav- 5 ing short screws.

The strings being held in both prongs cannot slip, and are at all timesheld taut and firmly.

Having thus described my invention, I claim as new and desire to secureby Letters Patent An agraffe having two prongs, each provided with aninclined aperture or inclined apertures, the central axes of the twocorresponding apertures in two prongs being on one and the same line,substantially as herein shown and described.

AUGUSTUS BAUS.
